<p>
 The `IsNonClientRegionSupportEnabled` property enables web pages to use the `app-region` CSS style. Disabling/Enabling the `IsNonClientRegionSupportEnabled` takes effect after the next navigation. Defaults to `FALSE`.

<p>When this property is `TRUE`, then all the non-client region features will be enabled: Draggable Regions will be enabled, they are regions on a webpage that are marked with the CSS attribute `app-region: drag/no-drag`. When set to `drag`, these regions will be treated like the window's title bar, supporting dragging of the entire WebView and its host app window; the system menu shows upon right click, and a double click will trigger maximizing/restoration of the window size.

<p>When set to `FALSE`, all non-client region support will be disabled. The `app-region` CSS style will be ignored on web pages. \snippet SettingsComponent.cpp ToggleNonClientRegionSupportEnabled </p>
